Improving cutting tool productivity by optimizing lubrication and geometry
During processing, the material is sheared off and then slides towards the cutting surface, generating a high level of friction on it. Without lubrication, the heat generated by the machining process quickly becomes too great and leads to the deterioration of the cutting edge, or even its destruction. One of the major roles of the lubricant is to reduce the friction of the chip on the cutting face, but also to dissipate the heat generated by chip formation. For best results, the lubricant jet must be directed precisely at the interface between the chip and the cutting surface and must also have optimum pressure and velocity.
The solution adopted by DIXI Polytool is the integration of the patented "Cool+" coolant system at the interface between the chip and flute face. This is made easy by the use of a coolant hole towards the flute, through which high speed lubricant flows. However, this solution is not applicable for small milling tools (Ø<6mm) because the size of the internal lubrication hole causes too much stress in the milling cutter, leading to immediate breakage as soon as the tool is machined.
DIXI Polytool had the idea of improving this system by adding a ring at the outlet of the spray channels, thus allowing acceleration and concentration of the fluid towards the cutting zone.
